SPECIFICATION forming part of Letters Patent No. 596,765, dated January4, 1898.

Application filed May 1, 1896. eriallio. 589,897. (No model.)

To all whom, it may concern.-

Be it known that I, ANDREW E. VEON, a citizen oi the United States,residing at Brainerd, in the county of Crow Wing and State of Minnesota,have invented certain new and useful Improvements in Vapor-Lamps, ofwhich the following is a specification.

My invention relates to lamps, and more particularly to lamps forheating purposes and in which a light hydrocarbon is used and vaporizedby the heat of the lamp, and has for one of its objects to provide alamp which will produce an intense heat and at the same time will beentirely free from any liability to explode.

Another object oi my invention is to provide a lamp that may be readilyand safely carried in a trunk or traveling bag or outfit without beingbroken and without spilling or wasting the hydrocarbon with which it maybe filled.

Another object of my invention is to provide a lamp which. will notconsume thewick or wicks used therein and which will require no furtherattention than keeping it supplied with the material burned therein andlighting and extinguishing it.

Still another object of my invention is to provide a lamp which willconcentrate or focus the flames and heat produced thereby and maintainthe same at substantially an unvarying height.

These objects I accomplish in the manner and by the means hereinaftermore fully described in detail, reference being made to the accompanyingdrawings, in which similar letters of reference indicate correspondingparts in all the figures of the drawings, in which Figure l is a sideelevation of my improved lamp. Fig. 2 is a vertical sectional View ofsame on the line a; w of Fig. l, with the cap I removed. Fig. 3 is a topplan view on an enlarged scale. Fig. 4 is acen'tral sectional view oftube In carrying out my invention I provide a reservoir A, preferably ofcylindrical form and made of brass or any suitable material and havingfixed in its upper end by means of screw-threads a cap B. Centrallyfixed in the cap 13 by any suitable means is a tube 0, connecting withthe interior of the reservoir A and rising vertically from the captherein. The tube 0 is of the same diameter throughout its length and isopen at each of its ends. The top of the tube is provided with a numberof inwardly-projecting points D, formed on the upper end of the tube Gby recessing the end of the tube at regular intervals and to the samedepth and bending the projecting points or ends-produced thereby in thedirection of the center of the tube 0. Concentrically mounted in tube 0is a second tube E, supported therein by the projecting points D. Thistube E is entirely open at its lower end, but has its upper end formedwith a cap like the end of a closed thimble and is provided with a smallorifice F in the center of the cap. This central tube E is of the samediameter from its lower end to where its sides begin to contract to formthe closed or thimbio-capped end thereof. Tube 0 has fitted to its innercircumference a wick G, which extends down in the reservoir. The tube E-is also provided with a wick H, extending into the reservoir. After thewick is inserted in the tube 0 the second tube E is pushed through thetube 0 until it projects a slight distance beyond the upper end thereof,it being held securely therein by the contact of the wick in tube 0against its outercircumference and the inwardly-projecting points D,formed in the end of the tube 0. The wick G in the outer tube 0 is notcarried to the extreme top thereof, but rests at a point where the flameof the burning fluid does not reach it nor char it. The wick in theinner tube E is not burned, and neither of the wicks G and H will needrenewing if they are properly adjusted in their respective tubes. W'henthe reservoir A is supplied with a suitable hydrocarbon and the wicksand tubes properly adjusted therein, the application of a light to theend of the tube 0 will produce a flame which in turn vaporizes the fluidwithin the upper end of the tube E and forces a jet of vapor through theorifice F in the end of the tube and which is in turn ignited. The heatsurrounding the tube E, produced by the flame at the top of the outertube 0, will cause the flame of the vapor issuing from the orifice inthe tube E to be projected vertically to a distance of several inches.The height of the flame proof the hydrocarbon-flame and of the vapor-This construction not only utilizes duced at the end of tube E dependsupon the distance that this tube projects abovetubc 0. Increasing theheight of tubeE increases the length of the flame arising therefrom.This jet of burning vapor formsthe central part of the flame produced bythe lamp and lifts the flame arising from the outer tube i T reservoir,but it is obvious that the shape and dimensions of the rerservoir mayvary with-' and carries it upward, the result being acsteadier and moreintense flame than is possible with asingle-wick tube.

The hydrocarbon which I prefer to use in my improved lamp is alcohol;but it makes no material difference whether the alcohol used is madefrom wood or grain so far as being, however, moreeconomicalto usewoodalcohol.

A cap I is provided for covering the ends of both of the tubesto preventthe escapeof the fluid therefrom.

I am aware that it is not new to construct a vapor generator and burnerhavinga central tube mounted in a wick-tube for generating the vapor,the central tube having a hollow cylinder mounted on its top andprojecting around its sides to a distance therefrom, the cylinder havingapertures in its circumference from which the vapor is projectedhorizontally, and-I am also aware that itis not new to surround acentral tube thus constructed with a series of tubes the flames fromwhich are directed against the lower end of the cylinder. Suchconstructions instead of concentrating all of the flames and the heatproduced by the lamp at a point above the end. of the central tube andrendering it possible to utilize both the heat and flame thereof, as isthe result in my construction, radiates both heat and flame from acommon center and renders such a lamp-useless for the purposes of myinvention.

The essential feature of my invention consists in using the flamefrom aWick-tube surrounding a tube provided with a Wick rising near its upperend, said end being closed with a cap having a vent or orifice thereinto. permit the escape of a jet of vapor, saidvapor-tube adj ustablysupported within the wick-tube-with its top a distance above thewick-tube whereby the flame and heat of the vapor and the flame and heatfrom the wicktube are united and concentrated and the united flamessupported at a uniform height, the height depending on the height thevaportube rises above the outer tube. This fea:

ture utilizes in a concentrated form the heat flame.

driven away from the center the vapor-flame to draw the hydrocarbonflameto itself, but also draws or sucks the oxygen of the-air intothe flame,whereas in the usual construction the air is forced or from which theflames are radiated.

I have shown and described a cylindrical out departing from theprinciples of my invention. The direction in which the tubesproject'from the reservoir may also vary, and

curved tubes may be used instead of straight j Ones;

concerns the quantity of heat produced, it

I claim as new, and desire to secure by Letters Having thus described myinvention, what Patent, is

1. A vapor and hydrocarbon burner consisting of a wick-tube, open at itsupper end, carrying a wick and connected with a hydrocarbon-reservoir, acapped tube adjustably supported in said wick-tube, and a vent inthemiddle of said cap, substantially as shown and described.

'2. In a vapor and hydrocarbon burner for uniting and concentratingtheheat and flame of a hydrocarbon with the heat and flame of a jet ofvapor produced thereby, the combination with a wick-tube open at itsupperend and'connected at its lower end with a hydrocarbon-reservoir, ofa tube having its upper end closed with a cap, and having a vaporvent inthe center of the top of said cap said tube being adjustably supportedwithin said wick-tubewith its capped end rising above said wick-tubewhereby the flame of the hydrocarbon and the flame of the jet of vaporproduced thereby are united and the hydrocarbon-flame supported by thevapor-flame substantially as shown and described.

3. A lamp consisting of a reservoir A, a cap aB secured to said:reservoir, a tube G secured 'insaid cap and carrying a wick G, said tube'provided with inwardly-turned projections -D, at its upper end, asecond tube E, capped at its upper end and provided with an orifice F inthe topof said cap, said tube carry- I ing a wick H1, and concentricallysupported within the first tube between the projecting points therein,substantially as shown and described.

Intestimony whereof I hereto affix my signature in the presence of'twowitnesses.
